According to Dell's online store, Windows 8 apps will be capable of being "run on and synced" to the Xbox One



From Engadget:

"Now your phone, desktop, tablet and TV can all give you a unified web and entertainment experience," it says. Although this aligns well with some of the company's goals, we'd still take it with a grain of salt -- Microsoft has said in the past that the Windows 8 apps won't be cross-compatible with the Xbox One without extra tweaking. It's not clear if the Dell statement is a misunderstanding, or merely a suggestion that app data will sync across devices to provide a more seamless experience.
